Application filed July 25, 1923. Serial No. 653,650.

To all whom it may concema p Be it known that I, LOUIS ROUANET, citizenof the French Republic, residing at Ivry-Port, Seine, in the FrenchRepublic, have invented new and useful Improvements in Removable Wheels,of which the following is a specification. 4

The present invention relates to a removable wheel for motor vehicles orthe like, of the type comprising a wheel hub whereupon series ofmetallic wire spokes, connecting the hub to the tire carrying rim, areattached, said hub comprising an annular part or flange by. means ofwhich it can 'be readily I mounted, by means of bolts and nuts or anyother known attaching means, on a flat collar provided on the centralhub permanently mounted on the vehicle axle.

The accompanying drawing shows by way of example an embodiment of thewheel according to the invention.

In Fig. 1, the upper half of the fi re is a. cross section of the wheelmounte on the axle hub, and the lower half shows the wheel hub in sideView. i

Fig. 2 is a partial elevation'of the central part of the wheel proper.

The wheel hub a is made of 1i ht cast metal, preferably" of the Alpaxwhich is now on sale on the market. Said hub is made with a flat annularflange I) provided with a series of apertures 0 disposed on' a circleandthrough which the boltscl receiving the nuts e may extend. These boltsand nuts constitute the means for securing the wheel to the collar partf of the permanent hub 9 carried by the front or rear axle of a car. Thepart a of the hub,

adjacent to the flange b constitutes a very thick rib having asemi-circular shape, which. provides for a great resistance, whilehowever keeping a certain elasticity. Said rib is thicker than the parti of the hub and 4 than the flange b, with a view to increase theresistance while at the same time reducingto a minimum the weight of thewhole hub. Moreover, said rib affords a good pro-.

alloy tection for the bearing surfaces b of the hub flange againstaccidental shocks when the wheel is dismounted. The bearing surfaces bare formed into bosses 12 provided on the outer face of the flange b.The length of the part i of the hub is greater than the width of the rimand has the shape of a cup with substantially convex wall, its thicknessgradually decreasing towards the inner side of the wheel. To the part'2', are attached three series of spokes j, is, Z whichconnect the hub ato the rim m carrying the tire n.

The series of spokes j and k, which serve particularly to transmit thedriving and braking stresses, are disposed according to a triangle, asshown in the drawing, the triangle having its apex at 0 on the hub, andits base 31-11 on the rim. The series of spokes Z, which withstandsparticularly the lateral thrusts, is much inclined from the exterior tothe interior; the spokes of this series are attached at 1', on the bodyof the huh (1, adjacent the flange b. The distance o-r being relativelygreat, the wheel has a great resistance. 7

Having now described my invention, what I claim as new and desire tosecureby Letters Patent is: In a wheel with metal wire'spokes forvehicles, a hub of light cast metal the length whercotis reater than thewidth of the rim of the wheeI, said hub comprising a substantiallyconvex part whose thickness decreases towards the inner side of thewheel, a fiat annular flange and an annular rib having a semi-circularcross-section. and connecting said convex part to said flat annularflange,

t he thickness of said rib being greater than that of the two latterparts, apertures provided in said flat annular flange and adapted forthe passage of securing bolts, said flange carrying bosses around saidapertures and conical bearing surfaces for the securing bolts beingprovided insaid bosses.

In testimony whereofI have signed my name to this specification.

LOUIS ROUANET.
